Structure of sulphur dioxide:

(i) The structure of SO

2

molecule is V-shape with S−O−S bond angle 119 and bond dissociation enthalpy is 297kJ/mol.

(ii) In SO

2

, each oxygen atom is bounded to sulphur by a ρ and a π bond and the ρ bonds between S and O are formed by sp

2

-p overlapping.

(iii) Sulphur in SO

2

is sp

2

hybridised forming three hybrid orbitals. Due to lone pair electrons, bond angle is reduced from 120 to 119.

(iv) One of π bonds is formed by pπ−pπ overlapping while other π bond is formed by pπ−pπ overlap
